Anterior Mediastinal Extension of Primary Chest Wall Infections: Role of Spiral CT in Detection and Management

A többszeletes spirál-CT-berendezések széles körű alkalmazása és a perfúziós szoftverek bevezetése lehetővé tette az agyi véráramlás CT-vizsgálatát. Cél és módszerek: A szerzők ismertetik az agyi perfúziós CT-vizsgálatok elvét, technikáját, amelyet az elmúlt másfél évben 96 betegükön végzett vizsgálatuk tapasztalataival egészítenek ki. A folyamatos technikai fejlődés eredményeként a közeljövőben lehetővé válik a teljes agy perfúziós CT-vizsgálata. Következtetések: Az agy perfúziós CT-vizsgálata gyors, viszonylag olcsó és a stroke kórismézésében pontos diagnózist eredményez.

Abdominal Ultrasound Examination

Purpose: To describe a case of endoluminal graft exclusion of a proximal para-anastomotic pseudoaneurysm that occurred 17 years following aortobifemoral bypass for occlusive disease. Methods and Results: The lesion was found on abdominal ultrasound examination as part of a work-up for acute abdominal pain and upper gastrointestinal bleeding in a 67-year-old male. A 5-cm saccular pseudoaneurysm was confirmed by preintervention aortography and spiral computed tomography (CT) scanning. Because of the patient's acute symptoms and high-risk medical condition (cardiomyopathy), he was deemed a candidate for endoluminal bypass. At the time of intervention, intravascular ultrasound (IVUS) interrogation identified a 3.5-cm-long separation of the existing aortic graft from the proximal aortic stump with a large pseudoaneurysm. The lesion was isolated and repaired by placement of an aortic-to-right iliac endoluminal bypass, ligation of the left limb of the aortofemoral graft, and femorofemoral bypass to restore blood flow to the lower extremities. Spiral CT scans at 48 hours and 3 months following the procedure confirmed complete isolation of the lesion. Conclusions: This case illustrates the feasibility of endografting for repair of aortic para-anastomotic pseudoaneurysms, and it also highlights the potential role of IVUS imaging in endoluminal graft deployment.

Mummy 527 B* belongs to the “Giovanni Marro” Egyptian Collection of the Museum of Anthropology and Ethnography of the University of Turin. This mummy of a oneyear- old pre-dynastic child was found in Gebelein in 1935 in a small necropolis discovered during excavations of the “Missione Archeologica Italiana” led by G. Farina, the new Director of the Egyptian Museum of Turin, with the participation of Prof. G. Marro as anthropologist. A whole body spiral CT scan with thin slices (1,00 mm thickness, 0,5 mm reconstruction interval) was followed by multiplanar and 3D reconstruction. The aim was to evaluate the child’s age at death and the presence of lethal pathologies. This study confirms the fundamental role of non-invasive techniques in the study of such rare pre-dynastic specimens.

Wall Oscillation

Purpose: patients with neuromuscular diseases presents an high incidence of respiratory infections favoured by stagnation of deep bronchial secretions and deficit of cough. The aim of the study is to evaluate the correct treatment of this condition and the role of High Frequency Chest Wall Oscillation (HFCWO) in helping the removal of bronchial secretions and reduce the incidence of infections in patients with neuromuscular disease. Methods: analysis of the current bibliography related to respiratory infections and neuromuscular disease. PCEF (Peak Cough Expiratory Flow) is used as a standardized indicator of efficiency of cough. Results: the High Frequency Chest Wall Oscillation (HFCWO) is useful, in cases of increased production of mucus and impairment of muco-ciliary clearance, to remove the tracheobronchial secretions and reduce the incidence of infections. Conclusions: the correct approach to patients with neuromuscular disease and frequent respiratory infections is focused on treatment of cough ineffective and management of bronchial secretions. High Frequency Chest Wall Oscillation (HFCWO) (VEST) has a central role in treatment of cough ineffective and management of bronchial secretions reducing respiratory infections.

Inspiratory Resistance

Normal subjects preserve tidal volume (VT) in the face of added inspiratory resistance by increasing maximal amplitude and duration of the rising phase of respiratory driving pressure (DP) and by changing the shape of this phase to one that is more concave to the time axis. To explore the possible role of chest wall afferents in mediating these responses, we determined averaged DP in eight quadriplegic subjects during steady-state unloaded breathing and while breathing through an inspiratory resistance (8.5 cmH2O X 1(-1) X s). As with normal subjects, quadriplegics preserved VT (loaded VT = 106% control) by utilizing all three mechanisms. However, prolongation of the inspiratory duration derived from the DP waveform (+22% vs. +42%) and shape response were significantly less in the quadriplegic subjects. Shape response was completely absent in subjects with C4 lesions. The results provide strong evidence that respiratory muscle spindles are responsible for shape response and that changes in afferent feedback from the chest wall play an important role in mediating inspiratory prolongation.

Pleural Surface

To address the role of the parietal pleura in reduction of mesothelial shear stresses during breathing, we measured the stiffness of the parietal pleural surface of mammalian chest walls using microindentation. The pleural surface was indented over ribs and intercostal spaces with rigid flat punches (tip radii of 0.01, 0.02, and 0.1 cm) to probe stiffness at length scales comparable with those of surface asperities. We found a tissue shear modulus of 6,700 dyn/cm2 and pleural membrane tension of 4,900 dyn/cm, with a geometric standard deviation of 0.42. These values are similar to those measured for the lung by Hajji et al., using indentation (Hajji MA, Wilson TA, and Lai-Fook SJ. J Appl Physiol Respirat Environ Exerc Physiol 47: 175–181, 1979). Surprisingly, the pleural surface over ribs and intercostal spaces exhibited similar stiffness. In addition, caudal regions exhibited lower stiffness than cranial regions. In the context of elastohydrodynamic lubrication, these results suggest that shear-induced pressures during breathing deform the chest wall and lung surfaces to a similar extent, promoting spatial uniformity of pleural fluid thickness and reducing shear stresses.
